Abstract

Physical database design tools rely on a DBA-provided workload to pick an "optimal" set of indexes and materialized views. Such an approach fails to capture scenarios where DBAs are unable to produce a succinct workload for an automated tool but still able to suggest an ideal physical design based on their broad knowledge of the database usage. Unfortunately, in many cases such an ideal design violates important constraints (e.g., space) and needs to be refined. In this paper, we focus on the important problem of physical design refinement, which addresses the above and other related scenarios. We propose to solve the physical refinement problem by using a transformational architecture that is based upon two novel primitive operations, called merging and reduction. These operators help refine a configuration, treating indexes and materialized views in a unified way, as well as succinctly explain the refinement process to DBAs. [ABSTRACT FROM AUTHOR]

31. Self-tuning Database Systems: Past, Present and Future.

Author

Chaudhuri, Surajit

Abstract

Although the goal of making database systems self-tuning remains elusive, there has been progress in this field in specific areas.We review some of these advances and also comment on directions that appear to be promising. In our view, the current architecture of the database systems makes building self-tuning database systems especially challenging. Therefore, it may be worth rethinking some of the key aspects of today΄s systems. Finally, we share our thoughts on opportunities and open issues, both in the context of self-tuning database systems, and the database field at large. [ABSTRACT FROM AUTHOR]
